About this trial

This clinical trial is a single-center, open-label, non-randomized first-in-human (FIH) study designed to evaluate the safety, tolerability, pharmacokinetics, radiation dosimetry, and preliminary efficacy of SNA028 (which is a two-step radioactivity pretargeting agents conducted by GPA33-CC and 177Lu-SmartD2) in patients with GPA33-positive colorectal cancer who have experienced disease progression/recurrence following prior standard therapy.
